Harsh or delayed engagement and shifts (2017–2023)
Ford TSB 23-2123 says some 2017–2020 F-150, 2018–2021 Expedition, Navigator and Mustang, and 2019–2023 Ranger vehicles with the 10R80 may have harsh engagement, harsh shifts or delayed shifts, possibly with a check-engine light, which may be due to the adaptive calibration being unable to adapt to hardware break-in; the fix is a main control valve body overhaul and/or an adaptive learning drive cycle. TSB 24-2254 covers some 2020–2023 vehicles built on or before Aug. 15, 2022 and attributes the same symptoms to movement of the CDF clutch cylinder sleeve causing hydraulic leaks, fixed by replacing the clutch cylinder if needed.[1][2]
